Crown moulding

ABSTRACT

Crown moulding installations may include an anchor strip secured along a wall and a moulding strip secured to the anchor strip. Some embodiments of the crown moulding have a notch along the length of the moulding strip that receives a portion of the anchor strip to position the moulding strip. Some embodiments of the crown moulding have a notch along the length of the anchor strip that receives a portion of the moulding strip to position the moulding strip. Installation of the crown moulding may be accomplished by measuring a predetermined distance from the ceiling, affixing the anchor strip at the predetermined distance, and affixing the crown moulding to the anchor strip. The predetermined distance may be calculated according to a desired crown moulding spring angle, the width of the moulding strip, and the thickness of the anchor strip.

TECHNICAL FIELD

The present disclosure relates generally to the moulding components. In particular, the present disclosure relates to crown moulding strips and other similar trim and/or finishing strips.

DESCRIPTION OF RELATED ART

Commonly, crown mouldings comprise decorative plaster or wooden trim installed where walls meet ceilings. In some cases, crown moulding components are manufactured from plastic, foam, or engineered wood products such as medium-density fibreboard. Crown moulding may typically be installed at an angle to both the wall and the ceiling surfaces, leaving a void behind the moulding and between the moulding, wall, and ceiling that has essentially a triangular cross-sectional shape.

Because the crown moulding is not typically installed flush against the wall or the ceiling, installation can present challenges, both for novice do-it-yourselfers and for experienced installers. Typically, the installer must figure out the height where the moulding strip would abut the wall, which may be dependent upon the intended crown angle and the width of the crown moulding strip. Such problems may increase the time and/or cost of crown moulding installation. Miscalculations by the installer may lead to wasted materials, lost time to correct errors and/or redo installation steps, and misaligned moulding pieces.

Some crown moulding installations include a layered crown design, where multiple strips are stacked to provide a more complex appearance than a single moulding strip. In such installations, the aforementioned difficulties in installing a crown moulding are exacerbated by the number of layers to be built up.

SUMMARY

In one embodiment, a method of installing a crown moulding is disclosed. The method includes affixing an anchor strip along a wall, inserting a portion of one of the anchor strip and a moulding strip into a notch, and affixing the moulding strip to the anchor strip.

In another embodiment, a method of installing a crown moulding is disclosed. The method includes providing an anchor strip having a cross-sectional profile, providing a moulding strip having a cross-sectional profile, wherein one of the anchor strip cross-sectional profile and the moulding strip cross-sectional profile has a notch along its length, affixing the anchor strip to a wall, and inserting a portion of one of the anchor strip and the moulding strip into the notch, thereby abutting the moulding strip to the anchor strip.

In another embodiment, crown moulding components are disclosed. The crown moulding components include an anchor strip and a moulding strip. One of the anchor strip and the moulding strip has a notch along its length. A portion of one of the anchor strip and the moulding strip is adapted to be seated in the notch.

Embodiments of the present disclosure comprise crown moulding components and methods of installing the same. In the present disclosure, reference to crown moulding component may include moulding strips, also commonly known as molding or coving, or other types of finishing strips and/or millwork components. Such millwork components may be manufactured from wood, reformed or engineered wood, plastic, plaster, foam, composites thereof, or other materials.

In various embodiments, a crown moulding installation according to the present disclosure includes an anchor strip affixed to a wall and a moulding strip affixed to the anchor strip. In one embodiment, a notch or cut-out along a length of the moulding strip receives a portion of the anchor strip, thereby providing a relatively easy fitment process and essentially flat nailing surface. In other embodiments, a notch along a length of the anchor strip receives a portion of the moulding strip. In various embodiments, various planar surfaces of the anchor strip abut corresponding planar surfaces of the moulding strip to provide a stable and secured install. In other embodiments, one or more curved surfaces of the anchor strip abut corresponding curved surfaces of the moulding strip to provide a stable and secured install. In various embodiments, anchor strips and/or moulding strips may be manufactured in milling or shaping operations already known in the art or not yet known in the art.

As used herein, the term “anchor strip” may include a millwork component adapted to be affixed horizontally along a wall where crown moulding is to be installed. In embodiments, an anchor strip may be installed with a vertical offset from the ceiling, wherein the size of the vertical offset is dependent upon various parameters of the crown moulding installation. According to various embodiments, a crown moulding strip may be anchored to the anchor strip. Embodiments of anchor strips include a notch adapted to receive a portion of the crown moulding strip. In other embodiments, an anchor strip includes a portion that may be received by a notch on a crown moulding strip.

Referring now to FIG. 1, a cross-sectional view of installed crown moulding according to one embodiment is depicted. As shown in FIG. 1, a moulding strip 100 is affixed to an anchor strip 110, which itself is affixed to a wall 120. The moulding strip 100 spans a space between the anchor strip 110 and a ceiling surface 130. Various embodiments of moulding components comprise one or more decorative profile faces 106. Embodiments of anchor strips comprise a decorative profile face 116. Profile faces 106, 116 may include similar or complementary design elements such that when moulding strip 100 is installed on anchor strip 110, the combined anchor strip 110 and moulding strip 110 form a cohesive built-up appearance.

As shown in FIG. 1, embodiments of crown moulding strips 100 are installed with a spring angle of approximately 38 degrees. As used in the present disclosure, the term “spring angle” indicates an angle between the crown moulding and the wall on which the moulding is installed. Alternatively, the spring angle indicates the angle between the crown moulding and a vertical plane. The spring angle may also be known as a crown angle.

Referring to FIG. 2, moulding strip 100 further comprises a notch 105 comprising two adjacent surfaces at an angle to each other. In the embodiment depicted, the two adjacent surfaces comprise vertical and horizontal planar surfaces at a 90 degree angle to each other. In other embodiments, other orientations and/or angles of the adjacent surfaces may be utilized. In various embodiments, the surfaces that form the notch 105 comprise substantially flat surfaces. As shown in FIG. 1, the orientation of the notch 105 is such that when moulding strip 100 is placed on anchor strip 110 mounted to wall 120, moulding strip 100 is at the spring angle relative to wall 120. Further, in embodiments, top surface 107 is approximately parallel and adjacent to ceiling 130 due to the spring angle, width of moulding strip 100, and angle of top surface 107.

In alternative embodiments, a notch may comprise adjacent surfaces that intersect at angles other than 90 degrees. For example, some embodiments of the present disclosure include a notch formed by surfaces intersecting at an acute angle. Other embodiments include a notch formed by surfaces intersecting at an obtuse angle. Other embodiments include a notch formed by composite and/or curved surfaces.

Referring to FIG. 3, moulding strip 100 may be installed on anchor strip 112. As shown in FIG. 3, the profile face of anchor strip 112 is elongated in comparison to anchor strip 110. As would be understood by a person with ordinary skill in the art having the benefit of this disclosure, a group composed of a wide variety of anchor strips and moulding strips may have various shapes and sizes, and such components may be respectively interchangeable with other anchor strips and moulding strips, provided that the notch shape is substantially common across the group. As shown in FIG. 1 and FIG. 3, moulding strip 100 has a spring angle of approximately 38 degrees, primarily due to the vertical placement of the respective top surfaces of anchor strip 110 or 112, the horizontal offset of the notch from the wall 120 resulting from the thickness of anchor strip 110 or 112, the width of moulding strip 110, and the size and shape of the notch 105. Thus, a variety of moulding strips may be compatible with a variety of anchor strips to result in a variety of spring angles, given the foregoing parameters are essentially kept constant within the group.

Referring to FIG. 4, an installed moulding strip 101 is shown having a spring angle of approximately 45 degrees. As shown in FIG. 4, the spring angle of moulding strip 101 results from a combination of the vertical position of anchor strip 110 (particularly, the vertical position of the top surface of anchor strip 110), the width of moulding strip 101, the thickness of anchor strip 110, and the size and shape of the notch of moulding strip 101. Further, in embodiments, the top surface of moulding strip 101 is approximately parallel and adjacent to ceiling 130 due to the spring angle, width of moulding strip 101, and angle of the top surface.

Referring to FIG. 5, moulding strip 102 is installed with anchor strip 113. As shown in FIG. 5, moulding strip 102 has a notch with a curved surface 108 that interfaces with curved surface 118 of anchor strip 113. Accordingly, moulding strip 102 and anchor strip 113 comprise one example of anchor strips and moulding strips that have corresponding cross-sectional shapes. In other embodiments, other curve radii or other various shapes may be selected for moulding strip and anchor strip matching pairs.

Referring to FIG. 6, a moulding strip 103 and anchor strip 110 installation is depicted. As shown in FIG. 6, moulding strip 103 comprises a relatively shallow notch 109. FIG. 6 thus illustrates that a variety of notch sizes and shapes fall within the scope of the present disclosure.

Various embodiments of the present disclosure may include crown moulding installed at virtually any spring angle. As set forth above, the spring angle of a crown moulding may be determined by a number of parameters including the notch shape and size, vertical position of the top surface of the anchor strip, the width of moulding strip 101, the thickness of anchor strip 110, and the size and shape of the notch. In particular, moulding strips may be designed for spring angles of approximately 38 degrees, 45 degrees, or 52 degrees.

Referring to FIGS. 7 and 8, embodiments of the present disclosure include moulding strip 104 and anchor strip 111. As shown in FIGS. 7 and 8, this embodiment includes a notch 115 on anchor strip 111, while moulding strip 104 has no such notch. Lower end 119 of moulding strip 104 is adapted to be received by notch 115. Various embodiments of the anchor strip may have a wide variety of notch size and shapes to complement corresponding lower ends of moulding strips.

In operation, an anchor strip and a moulding strip may be installed on a wall to form a built-up appearance where the wall and a ceiling meet. The anchor strip and moulding strip may be selected for their appearance, size, spring angle, and other desired parameters according to one's particular preferences. In embodiments, the anchor strip can be affixed to a wall at a predetermined height. In embodiments, the predetermined height of the anchor strip can be measured as a distance from the ceiling. As set forth in greater detail above, the predetermined distance may be calculated according to various parameters such as moulding strip width, spring angle, anchor strip thickness, and size and/or shape of the notch. Accordingly, an installer may measure and then mark the predetermined anchor strip height, cut the anchor strip to length, and fix the anchor strip to the wall at the predetermined height. In one embodiment, an installer can mark the anchor strip height with a laser level or other light-based markers. In other embodiments, the installer can mark the anchor strip height with a chalk line, pencil, or other marking instruments.

In some embodiments, the anchor strip is installed by affixing to wall studs or other structural members.

Following installation of anchor strip, the installer may then cut the moulding strip to length, cope or miter the ends of the moulding strip (as called for by the crown moulding setting), and affix the moulding strip to the anchor strip. In embodiments where the moulding strip has a notch, the installer may place the moulding strip on the anchor strip by inserting the appropriate anchor strip portion into the notch so the moulding strip is seated on the anchor strip. In embodiments where the anchor strip has a notch, the installer may place the moulding strip on the anchor strip by inserting the appropriate moulding strip portion into the notch so the moulding strip is seated on the anchor strip. In embodiments, the moulding strip may span the length from the anchor strip to the ceiling at the desired spring angle when properly seated on the anchor strip.

In embodiments, the installer can affix the moulding strip to the anchor strip by driving nails through the moulding strip and into the anchor strip. In other embodiments, various types of fasteners and/or adhesives may be utilized to secure the moulding strip to the wall and/or anchor strip. In some cases, the installer may affix the moulding strip to a ceiling surface and/or ceiling joists with mechanical or adhesive fasteners.

Embodiments of the present disclosure may include moulding strips and/or anchor strips of virtually any desired thickness, width, and/or length. Embodiments of the present disclosure may be manufactured in a moulding machine or other type of milling or shaping operation. Embodiments may be coated with primer, paint, and/or other various coatings as would be understood by a person of ordinary skill in the art. In some embodiments, moulding strips and/or anchor strips are coated only in a primer or similar coating prior to installation. Following installation, the moulding strips and/or anchor strips may then be caulked and/or painted. In various embodiments, the installer can apply caulk to nail holes, joints, and/or seams. The installer may also sand the installed moulding strip and/or anchor strip and finish by applying coats of paint.

Embodiments of the present disclosure may present several advantages over prior art methods. For example, utilizing methods disclosed herein, crown moulding may be installed in less time than traditional techniques, which may result in reduced labor-related costs.
